C50 – ø x 2.7

Carbon Fiber Reinforcing Grids for Concrete Structures

DESCRIPTION C-GRID® C50 – ø x 2.7 is one of the C50 Series of high strength carbon fiber/epoxy grids for reinforcing concrete structures.
Large high strength carbon strands are aligned in both longitudinal and transverse directions.

Features

Applications

Non-corrosive; can be used with as little as
1⁄4” (6 mm) of cover

Slabs-on-grade

Requires less concrete cover leading to
lighter structures

Marine structures

Thin topping slabs and overlays

Lightweight, easy to handle and use; can be
cut to fit using conventional tin snips

Silos and concrete storage tanks

High tensile strength and modulus

Balconies

Outstanding mechanical bond with concrete;
requires a mimimum 1⁄4” (6 mm) to develop
its strength

Precast concrete, including architectural
and wall panels

Concrete repair and shotcrete

PHYSICAL PROPERTIES
carbon fiber with glass fiber support and epoxy resin

Application Use Note: C-GRID® remains a relatively novel material without the extensive performance history of traditional construction materials. Reported properties are average values, not design values. Structures and applications
using C-GRID® should be designed using appropriate safety factors or load and strength reduction factors. All applications utilizing C-GRID®, including critical life safety and fire rated structures, should be designed and reviewed by a
licensed engineer experienced with FRP materials. The data expressed herein is believed to be accurate at the time of publication; however, it is subject to change without notice.

Notes:
Centerline-to-centerline spacing between strands is nominal and based on the average number of strands per unit width. Actual spacing may vary by ± 0.10” (± 2.5mm).
The longitudinal direction is in the direction of the roll, and the transverse direction is across the width of the roll. For example, if a roll of C-GRID® is 47.5” wide, the carbon strands in the transverse direction are 47.5” in length. If
a roll of C-GRID® is 500 yards long, the longitudinal strands are 500 yards in length.
Individual strand cross-sectional area is normalized to the cross-sectional area of the fibers in accordance with ACI 440.2R. The actual measured thickness and width are larger and shall not be used for design purposes.
Reported tensile strengths are typical or average properties based on testing. Tensile modulus values are based on properties reported by the carbon fiber supplier. C-GRID® exhibits linear elastic behavior, so failure strains are
estimated using Hooke’s Law.
